Abstract: A delivery device may comprise a sheath configured to be inserted into a body lumen of a patient. The sheath may have a proximal end, a distal end, a first channel extending within the sheath from the proximal end to the distal end, and a second channel extending within the sheath from the proximal end to the distal end. A collective cross-sectional area of the first channel and the second channel may be more than 50% of a total cross sectional area of the sheath. The device may also be comprised of a handle at the proximal end of the sheath, wherein the handle is configured to provide fluid communication between a first port and the first channel and a second port and the second channel.

Abstract: Implementations of a delivery device and method are disclosed. One implementation is a delivery device comprising a flow chamber with an inlet port for receiving a fluid flow in the flow chamber, and an outlet port for exiting a material from the flow chamber. The flow chamber may include a formation portion in which a suspension of the material is formed, and a collection portion that directs the suspension toward and/or into the outlet port. An amount of the material may collect in the collection portion adjacent the outlet port. The device may further comprise an insertion port for permitting insertion of the material in the flow chamber, and/or a pusher operable to move the amount of material through the outlet port. Related devices and methods also are disclosed.
